PATENT OFFICE DIRECT AND MESNE ASSIGNMENTS, TO LIBERTY AMUSEMENT COMPANY, OF SAN J OSE, CALIFORNIA, A CORPORATION OF CALIFORNIA SPRAYING DEVICE i Application `ile. December 27, 1928. Serial No. 328,747.

It is one object of our invention to provide a device of the character indicated whereby a liquid may be discharged from a receptacle in a spray of any desired denseness without the use of valve of any kind.

It is another object of the invention to provide a device of the character indicated so constructed and arranged as to become operative or inoperative through tightening or loosening the grasp thereon as the case may be, thereby eliminating the necessity of providing a trigger operating mechanism, of the valve type.

It is still another object of the invention to provide a device of the character indicated that will be simple in construction, economical to manufacture, strong, durable, and highly eliicient in its practical application.

In the drawings:

Figure 1 is a vertical transverse cross-seo tion through one embodiment of the invention, partly in elevation.

Figure 2 is a plan view of a portion of a device showing another embodiment of the invention.

Figure 3 is a vertical cross-section through still another embodiment of the invention, partly in elevation.

Figure 4 is a detail plan view of a portion of the spring member shown in Figure 3.

Referring now more particularly to the drawings, we show at 1 a container for paint to be sprayed, and vertically mounted in the container is a tube 2 extending from a point near its bottom through its top and terminating in a nozzle 3.

At 4 we show a handle formed by bending a metal strap into the form shown, with one end as 5 secured to the top of the container 1, and the other end terminating beneath a horizontal part 6 as at 7 and to which it is securely fastened. Between the parts 6 and 7 is formed a bearing 8 lying in a plane parallel with the plane of the top of the container. Punched forwardly out of the angular grip portion of the handle is a stop as indi cated at 9.

At 10 is shown a tube terminating in a nozzle 11 and mounted on a trigger member 12 which in turn is journaled in bearing 8 and bears against the stop 9 when tube 10 is at right angles to tube 2.V

The tube 10 is connected to a source of air supply under pressure by means of a ieXible tube 18, and is normally held yat an angle t0 the tube 2 by means of a spring14 inserted between the tube 10 and part 6 of'handle 4.

When the device is constructed and assembl'ed as above set forth thetube 10 will normally lie at an angle represented by the dotted line 15, in which position air may be discharged at will through the tube and out of the nozzle 11. without eecting the discharge of liquid from container 1. This is a very desirable feature of this invention because it permits the use of compressed air for cleaning the article or surface to be sprayed and also permits the air to flow at a uniform pressure at all times, so that when it is brought into operative relation to the nozzle 3 there is no sudden burst of air under excessively high pressure tending to discharge an over supply of the liquid. By operating the trigger 12 the tube 10 may be gradually brought down into a vertical position relative to the tube 2, the air discharging from nozzle 11 gradually drawing the air from tube 2 and then the liquid which the air blast deposits in a spray upon the surface tobe covered. When the trigger is re#` leased the spring 14 automatically returns the tube to an inoperativeposition insofar as the discharge of liquid is concerned, but the air flow is not interrupted.

V In the form of the invention shown in Figure 1 the tube 10 isvmoved in the plane of the tube 2, but in the form shown in Figure 2 the tube 10 is mounted upon a handle part 6 that is pivotally mounted on the container top as at 16. In this construction the tube 1() may be swung into or out of an operative position relative to tube 2 as desiredbut in a plane at right angles to the plane of the tube 2.

In Figure 3 we show a still simpler and stronger embodiment of the invention. In this form the spring action is inherent in the handle itself',` one end of the handle being secured to the container 1 as at 17 ,and the other end having a slot as 18 formed therein to encompass the nozzle 3. The two ends of the handle are not connected as in Figure l, but the free end overlies the fixed end and may vbe moved relative to the iXed end through'` the resiliency oi" the part that is b graspedihythe hand. The tubelOds lixedly mounted on the handle part 6 by means=o a bracket asflS. A. set screW- 2() is mounted.

inthe partso that the iinalposition ofthe nozzle 11 may be set at will relative to the nozzle 8. In this embodiment the handle itself 'functions as a handle, as a trigger and as a spring, and its middle portion is formed to function as a supporting leg.` 21hy It isto be understood, of course,'that While We' have herein shown and described' certain specific embodiments of the' invention,

changes' in form, construction andY method of assembly' andi` operation may be made 20 Withir the seopeof the appended claims.
